WARP DYE BEAM Filed July 16, 1945 Patented Apr. 17, 1951 omen:

WARP DYE BEAM" Homer V. Lang, Charlotte, N; 0. Application July 16, 1945, Serial No. 605,253

1 I This invention relates to a warp dyeing beam head and more especially to a warp dyeingbeam head having the improvement of the circular flange on the head over which the perforated cylinder fits projecting further toward another war-pbeam head at the opposite end of the perforated cylinder thus giving a greater strength tothe'connection between the perforated cylinder and the warp beam head.

Dyeing beams are usually made with heads from twenty-eight to thirty-two inches in diameter, and the perforated cylinders usually run from eight inches in diameter to twenty-four inches in diameter. All of them are approximately fifty-four and three-eighths inches betweenthe heads. These beams are for dyeing warps, and there is usually disposed on one of these beams about four hundred pounds of yarn. This'yarn is wound onto thebeams on a warper, the perforated beam cylinder riding down on the drum of the warper at the beginning of the winding operation. This drum on which the perforated cylinder rests is five-eighths to threefourthsof an inch shorter than the inside length of the beam. By riding on the cylinder the warper drum'drives the beam and also gives it braking 'surface for stopping the cylinder if an end breaks down. By driving the beam from the warper drum, the heads are hanging down supported only by the ends of the perforated beam cylinder.

These perforated cylinders have their perforations usually seven-sixteenths of an inch in diameter on five-eighths of an inch staggered centers, but sometimes these perforations vary in size as well as in the manner of disposition. Perforations have to be all the way to the end of the cylinder in order for the yarn to dye right in the cornerwhere the cylinder joins the beam head.

Heretofore it has been common practice to make a shoulder about one half inch high, that is an annular shoulder around the inside surface of the beam head, and to assemble the cylinder over these annular projections or shoulders and then suitable bolts or tie rods are passed through the beam heads and in the space inside of the perforated cylinder to thus hold the heads and the cylinder in assembled relation. The perforated cylinders are usually made from stainless steel or some other non-corrosive material and are usually about one-eighth of an inch thick. In the severe service to which these beams are subjected, running at about five hundred revolutions per minute on high speed warpers, and then suddenly stoppingwhen an end breaks down, ,the'head being supported by the cylinder, there is a tendency to stretch the cylinder in the ends so that the heads become loose.

It is an object of this inventionto provide a warp dyeing means having a perforated cylinder and head members with the head members having annular shoulders projecting towards each other and over which the. endsof the perforated cylinder fit; the annular shoulders not only being grooved peripherally but also being grooved longitudinally and also having gaps cut therein whereby the dyeing fluid can pass throughthe perforations and grooves in these annular shoulders and out through the perforations;

It is another object of this invention to provide a warp dyeing beam comprising av pair of head members eachof which has an annular shoulder on the inside surface thereof over which a perforated cylinder is adapted to be fitted, the shoulders extending further inwardly than has heretofore been the case toprovide greater support for the ends ofthe perforated cylinder and said-annular shoulders having gaps cut therein and also having'a peripheral groove extending therearound on the exterior of the annular shoulders and also having holes extending through the shoulder members and said shoulder members on their exterior surface having longitudinally extending grooves so that dyeing or bleaching fluid can pass through the gaps cut in the shoulders and through the holes of the shoulders and through the longitudinally extending groovesin the shoulders and circulating laterally around the exterior of the shoulders and outthrough the perforations in that portion of, the cylinder which is fitting over the shoulders projecting from the beam head.

Some of the objects of theinvention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings in which:

Figure 1 is an elevation of a warp dyeing beam head showing the left hand end thereof in section;

Figure 2 is a view on-an enlarged scale looking along the line 22 in Figure 1 and showing portions of the head broken away and also omitting the perforated cylinder which is normally disposed therearound;

Figure 3 is an elevation of the right hand end of the warp dye beam in Figure 1 and showing the cylinder in section and portions of the head broken away.

Referring more specifically to the drawings, the I beam heads instead of having about one half inch annular rib projecting from the inner surface thereof and concentric with the center hole II, have an annular rib of about two or two and a half inches projecting therefrom, this rib being indicated by reference character I4. There is one on each of the heads 9 and ID and a perforated cylinder I5 is adapted to fit over these annular ribs I4 and against the beam heads 9 and I0. It is to be noted that the lead lining I3 of the inner surface of the beam heads instead of being disposed all the way in to where the rib I4 projects outwardly, stops short of this point so that the ends of the cylinder fit against the solid steel of the beam heads instead of against the lead which might give way and cause the connection between thecylinder I5 and the heads 9 and I to become loosened. These annular ribs I4 have suitable gaps I cut therein and also have suitable holes I I passing therethrough. The ribs I4 also have a peripheral groove I8 passing entirely around the exterior surface thereof and there are also longitudinally extending grooves I9 on the exterior of the ribs I4, these longitudinally extending grooves are bisected by the peripheral groove I8.

By having the annular ribs I4 much longer than on warp beams heretofore used, the weight of the warp beam resting on the warper drum is supported by these annular ribs I4 instead of having to be supported by the cylinder I5 which often gives way under this great load. It is also seen that the ribs I4 can project inwardly towards each other any desired length as the dyeing fluid, for example, when it is forced to the inside of the perforated case I5 will pass out through the gaps I6 and through the holes I! and also flow out along the longitudinal grooves I9 and then from all of these perforations and grooves the dye can flow along peripheral groove I8 and out along the perforation in that portion of the cylinder I5 which is disposed over the ribs I 4. Regardless of whether the fluid is flowing outwardly through the perforated cylinder or is reversed and flows inwardly through the yarn and through the perforated cylinder, the same is true in that the dyeing fluid or bleaching fluid whichever is used can have unimpeded flow through the perforated cylinder and through the openings in the rib I4 and through the grooves in rib I4 and thus the extreme corner portion of the yarn at the junction point between the heads 9 and I0 and the 4 perforated cylinder I5 will be dyed or bleached just as Well as the other yarn on the other portions of the cylinder.

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being defined in the claims.

I claim:

1. A warp dyeing beam comprising a pair of head members and a cylinder having spaced perforations throughout its length, the head mem bers each having an annular projection disposed on the proximate surfaces thereof and over which the ends of the perforated cylinder are adapted to fit, the annular projections having perforations therethrough through which the fluid in dyeing and bleaching may pass, the exterior of the annular projections having a peripheral groove therein and also having longitudinally extending grooves bisected by the peripheral groove, and means penetratin the head members and disposed on the interior of the cylinder for securing the heads against the ends of the cylinder.

2. A warp dye beam member comprising a perforated cylinder and a pair of head members, the head members having annular ribs projecting from the proximate surfaces thereof, the ribs having perforations therethrough and having a circumferential groove on thei exterior surface over which the ends of the perforated cylinder fit, whereby a treatin fluid may pass in either direction through the ribs and between the ribs and the perforated cylinder and through the perforations in the cylinder, and means penetrating the head members and disposed on the interior of the cylinder for securing the heads against the ends of the cylinder.
